I've been using the Remarks social podcasting app for the past week. They are trying to address the retention (for sure) and monetization (I assume they're going to roll out an ads platform) problems mentioned in the article.
I've been posting my thoughts as I listen and really like when the host is on the platform and I can react to their posts. Only challenge for me is that I listen to a lot of my episodes while driving and can't scroll through posts.
